Remotely-triggered IED's have emerged as a major threat in today's high and low intensity combat scenarios. Although their preparation is relatively easy, they are sometimes quite sophisticated, and finding ways to counter them is a high priority task. Elbit Systems has devised a modular, programmable multi-band radio-frequency jammer which denies the enemy use of selected portions of the RF spectrum in the jammer's vicinity. The new-generation IEDJ is intended for use in a vehicle-mounted configuration.
The IEDJ consists of multiple programmable RF modules housed in a single transit case and served by a common power supply. The system is controlled (i.e., on, off, or zeroize) by the vehicle's driver using a Remote Control Unit (RCU). As new threats are identified, the system is reconfigured by uploading new "waveform" software using an external laptop connected to the RCU's Ethernet port. The laptop computer is only required during software uploads.
The IEDJ operates as a waveform jammer, not a barrage jammer. Barrage jamming in this hardware is an additional capability that is not currently programmed. All bands can be enabled simultaneously. There is frequency overlap between some channels providing the capability to focus more RF power on a particular threat. Each of the RF bands has a separate, independent exciter and waveform generator, so the jammer can be operated band-by-band. Each band has the capability to output 100 watts (50dBm) average and the output power is controllable.
The programming of this signal into IEDJ primary unit is performed by an FSR or operator using a designated ruggedized lap-top with the approved software interface and management tools referred to as the IEDJ Graphical User Interface (GUI). The special design of the exciter enables a very "clean" waveform to be transmitted. This feature ensures the capability to maintain communications with a vehicle carrying a full power operating jammer on-board protecting the troops.
